Should I buy new crystal B4 selling chronograph?

[larrytudor]

After seeing that a Tudor chronograph just like mine recently fetched nearly $4,000 on eBay, I'm sorely tempted to put mine up for auction there.

However, the crystal has some light scratches that accumulated over the years (since 1980), and I wonder if collectors prefer the original crystal as-is or a new one.

FYI, this one has the black face, Big Block Rolex Oyster case, tachymeter bezel, and Jubilee bracelet. Unless it's hidden by the bracelet connection, I can't spot a number anywhere.
